So, hab mich heute mal mit Postfix beschäftigt.
Mails von der Kommandozeile schicken geht. DKIM klappt soweit auch. TLS zu meinem Postfix auch.
Daher bald mal Dovecot anschauen und dann Spamschutz rein.

Installed #Postfix and configured #DKIM and got #DNS configured and I can send an email from the server to my proton email and it no longer goes to the spam folder, it actually shows up in my inbox and I think cool, got it all set correctly.
But now I notice that it seems like any other address I try to email (not my proton email address) I get a bounce message saying the email address doesn't exist.
Any #email gurus got a suggestion for what I should be looking at?

@DigA_UniLeipzig alles ist besser als #MicrosoftExchange: Selbst nen alter #UltraSPARC-T2 mit #Solaris sowie #Postfix & #Courierist besser, weils nativ mit allen Clients.wie @thunderbird funktioniert.
Is it possible to send email over Tor? Normally, the answer is no, because .onion domains don’t have DNS records, and therefore, no MX records. However, I know Postfix supports manually setting next-hop servers in its config. Can one of those next-hops be a Tor address?
(EDIT: to clarify, this would be per-destination, not for all emails. For example, if Contoso.com’s mail server is also on Tor as contoso.onion.)
Obviously, this will break SPF, but DKIM would still work, in theory.
This isn’t for any real reason. Just a late night idea when I remembered PGP doesn’t encrypt most headers.
Question;
Should I upgrade my server from Ubuntu Server 22.04 to 24.04 ?
Running #Postfix #Dovecote #nginx #NextCloud #wordpress on it.
All running OK
Machine is an i5-6400 @ 2.70GHz with 16GB of DDR4

I've run my own mailserver for over 15 years without a gap, it's just in the 10 or so years of running the business my world started to ever-more revolve around Google so my own domains/etc fell by the wayside. So I do already have a sound #postfix setup running, and we #procmail at user-level to sort our various emails/domains into a Maildir structure... procmail is where we used to invoke #spamassasin and #clamav from IIRC.
